Dl‐3.5.3′.5′‐Tetramethyl‐Thyronin

Justus Liebigs Annalen der Chemie, 1957
Abstractdl‐3.5.3′.5′‐Tetramethyl‐thyronin (II) wird, ausgehend von 2.6‐Dimethylanilin, in 10 Stufen mit einer Gesamtausbeute von 5% d. Th. dargestellt. Seine Eigenschaften werden mit denen von dl‐Thyronin, dl‐Thyroxin, dl‐3.5.3′.5′‐Tetranitro‐thyronin und entsprechend substituierten Thio‐thyroninen verglichen.

Thyronines and thyronamines: dual modulators of synaptic plasticity, cognitive decline, and geriatric depression in the aging brain.

Behavioural Brain Research
The aging brain induces cognitive deterioration and geriatric depression via synaptic dysfunction, neuroinflammation, and bioenergetic failure. Recent evidence identifies thyroid hormones (thyronines: T3, T4) and their decarboxylated derivatives ...

Thyronin‐ und thyroxinähnliche Aminoalkohole, IV

Archiv der Pharmazie, 1968
AbstractAus 4‐Hydroxynorephedrin und 4‐Hydroxypseudonorephedrin werden über mehrere Reaktionsstufen DL‐erythro‐ und DL‐threo‐1‐[4′(4″‐Hydroxy‐3″5″‐dijodphenoxy)‐3′5′‐dijodphenyl]‐1‐hydroxy‐2‐aminopropan als thyroxinähnliche Aminopropanole synthetisiert. Durch katalytische Hydrierung werden diese zu den beiden diastereomeren Thyroninanalogen dejodiert.

Rapid stimulation in vitro of rat liver cytochrome oxidase activity by 3,5-diiodo-l-thyronine and by 3,3′-diiodo-l-thyronine

Molecular and Cellular Endocrinology, 1994
The effect of the iodothyronines (thyroxine (T4), 3,5,3'-triiodo-L-thyronine (L-T3), 3,5-diiodo-L-thyronine (3,5-T2), 3,3'-diiodo-L-thyronine (3,3'-T2), 3',5'-diiodo-L-thyronine (3',5'-T2), 3'-monoiodo-L-thyronine (3'-T1), 3-monoiodo-L-thyronine (3-T1) and thyronine (T0)) on rat liver cytochrome oxidase (COX) activity after their addition to rat liver ...

Biological Activity of 3,3′,5′-Triiodo-DL-Thyronine

Endocrinology, 1962
Experiments have been conducted to evaluate the thyromimetic activity of 3,3′,5′-triiodo-DL-thyronine in rats as determined by its ability to slow the rate of loss of thyroidal radioactivity after administration of I131 and its suppression of thyroidal 24-hour I131 uptake.

Mass spectral properties of volatile derivatives of thyronine (T0) and use of these in the study of thyronine excretion in eu-, hyper- and hypothyroidism.

Biomedical mass spectrometry, 1984
The mass spectral properties of four classes of derivatives of thyronine are discussed ( oxazolidinone , O-methyl oxazolidinone , O-acetyl oxazolidinone and N,O- diheptafluorobutyryl methyl ester). An assay for thyronine in human urine is described based on the N,O- diheptafluorobutyryl methyl ester.

Plasma Thyronine Levels in Carcinoma of the Breast and Colon

Archives of Internal Medicine, 1981
Plasma triiodothyronine (T 3 ), reverse T 3 (rT 3 ), thyroxine (T 4 ), total thyroid hormone-binding globulin (TBG) capacity, and serum albumin were assayed in patients with early and advanced breast and colonic cancer and in healthy women. Plasma T 3 levels were reduced in both breast cancer groups, but were reduced only in colonic cancer patients ...
